When a driver approaches the car and touches the door manage sensor, the car sends a signal to look for a matched key fob. If the fob is within range (usually about 3 to 5 feet), it reacts with a radio frequency (RF) signal including an unique security code.

Typical Symptoms of Keyless Entry Failure
Drivers may experience several distinct symptoms when the system begins to fail. Acknowledging these early can avoid a total lockout.

2. Low Vehicle Battery Voltage
Fiat automobiles are infamously conscious voltage fluctuations. If the 12V lead-acid battery in the engine bay is aging or has a low state of charge, the BCM might temporarily disable non-essential electronic systems-- like passive entry-- to conserve power for engine cranking.
3. Signal Interference
External electronic interference can "hush" the interaction in between the fob and the car. Typical sources include:
High-tension power lines.Cellular towers.Other electronic gadgets in the chauffeur's pocket (smartphones, RFID-blocking wallets).Inexpensive aftermarket USB chargers plugged into the vehicle's 12V socket.4. Faulty Door Handle Sensors
The sensors inside the door deals with are exposed to the components. Wetness, road salt, and extreme temperature level cycles can trigger the capacitive sensing units to fail or the electrical wiring harnesses within the door panels to corrode.
5. Body Control Module (BCM) Glitches
The BCM acts as the "brain" for the keyless entry system. Software application bugs or momentary glitches can trigger the module to stop processing entry requests. In many cases, a software application update from a Fiat car dealership is needed to remedy known communication mistakes.
